How can I reset the ECU for a t-jet in multiecuscan?
I have a paid version and I thought somewhere you could reset all adaptive parameters but I believe I had to relearn the climate control also?

Can this also be done by removing the battery cables?

Hi, I have some hesitastions problems with my Fiat Punto T-Jet (and with me some other on the dutch forum). The car seems to hesitate a little bit when pulling from 3th, 4th and even 5th gear. Feels like very little hesitations one after another. I decided to make a log of it, which i've added to th...

Hi, I have a 2009 Grande Punto t-jet which drives fantastic. Only 'problem' it has that is has some short hesitations when pulling hard in 3th, 4th and 5th gear also. Strange thing is that it isn't always, but most of the times it is. Had a powerbox for a short time and that made it even worse. Car ...

I've send my test file to some people and they all say this is the normal behaviour of the turbo charger. So there's no problem at all.

Still no suggestions people?

Can the wastegate cause the problem? May it not open enough on lower rpm?

I mounted the new boost pressure sensor and made a new graph with ecuscan, but still the same problem.

It has noticable too little power beneath 1750 rpm.

So today i cleaned the EGR as the boost pressure sensor as well. They were still pretty clear, but despite that i cleaned them with some brake cleaner. After that i made a test run again with the MAF connected and there's still a huge difference in actual and desired boost pressures till 3000 rpm. A...

Can a bad boost pressure sensor also cause this?

No one that can tell me why the values could be so different between the boost levels?

I've cleaned my EGR as turbo sensor as well past month. They were very dirty, but are now super clean. So the egr shouldn't cause the problem.

Any suggestions?
